COOLER.

SPECIFICATION forming part of Letters Patent No. 336,88Q, dated February1, 188?.

Application tiled April 152, 1886. Serial No. 198,523.

To ttZZ whom, it may concern;

Be it known that I, ANDREW J. ORR, of Syracuse, county of Onondaga, inthe State of New York, a citizen of the United States, have inventedcertain new and useful Improvements in Milk-Coolers, of which thefollowing is a specification, reference being bad to the accompanyingdrawings, in which- Figure l is a front elevation of the cabinet withdoors open; Fig. 2, a vertical transverse section of same; Fig. 3, avertical section on line at, Fig. 1; Fig. i, a horizontal section online yy, Fig. I; Fig. 5, a plan view of top of cabinet and refrigerating-pan, the cabinetcover being removed; and Fig. 6 is an isometric View ofmy U-shaped milk-can.

Similar letters or figures of reference indicate corresponding partsthroughout the several views.

My invention consists of a milk-can having inner vertical walls bentinwardly and forming a, U shaped millrchaniber. said walls beingparallel to the vertical side walls and connected to each other and tothe side walls by rounded connections, and having a flat open top, therecess extending up to the top.

My object is to improve the construction of the cooler by making thegreater part of the interior in removable sections to facilitatecleaning, and also to improve the milk-can by increasing the area ofcooling-surface, and also to obtain a how of the cooling-liquid aroundthe milk-can at all points of its outer surface, and especially in frontbetween the milk-can and the lining of the case. It is constructed asfollows:

A is the cabinet, consisting of a wooden case provided with transversejoists 1, upon which I mount the longitudinal stringers 2, the joistsand stringers together constitutin g an inclined supportingi'rame tocarry the water-tank 3, and located upon an incline above the bottom ofthe cabinet, about as shown, thus creating the chamber-l. Thiswater-tank is constructed of sheet metal, water-tight. I provide thiscabinet with doors in front to permit access to the faucets 5 6 and tothe chamber 4, as well as to observe the condition of the milk or creamthrough the glass ports of the case or watertank. This cabinet has alsoa removable cover to permit access to the ice-pan 7 and funnels 8. It isalso provided with a water-inlet, 9,

(No model.)

opening into the ice or water pan 7, and an overtlowpipe. 10, located atabout the top of the milk-can B.

B is my milk-can, constructed oisheet metal, with vertical sides orwalls and tight flat inclined bottom, which bottom is provided with thesupporting-ribs shown in Fig. 3. The walls of this can are bent inwardfrom one end so as to create a U shaped milkchaniber, the sides of whichchamber are separated by the walls 12 13, and these walls are separatedfrom each other to create a walerspace between them. This is theconstruction shown in Fig. 6 and at the left of Fig. 4.

In Fig. at I show two duplications or extensions of my construction, inthat the central milk-can is shown as having two sets of inwardlybentwalls, 12 13, creating three parallel mil k-chanihers communicating witheach other, and in the milk-can on the right I show three sets ofinward] y-bcnt walls, creating four parallel milk chambers, allcommunicating with each other. In either construction let is thefaucet-pipe, only one being necessary, even for the largest milk can.Upon these pipes I screw the faucets 5, the pipes extending down throughholesin the bottom of the watentank, provided with a suitable packing tomake a water-tight joint, and the faucets are removahly secured below,and when the faucets are unscrewed the milkcans can be lifted out of thecabinet for scalding or other cleansing.

In the front olthe milk-can I cuta vertical port or slot, which I coverand close with a sheet of glass, 15, making a watertight joint in anydesired manner. This slot and glass 15 extends from the bottom to thetop, or very nearly so, and the glass permits the inspection of thecream.

In the side of the watcrtanlr I cut also a. vertical port or slot, whichis covered by a sheet of glass, 16, mounted thereon by a watertightjoint in any ordinary manner, and these glasses 15 16 coincide with eachother.

In the bottom of the water-tank I insert a draw-off pipe, 18, upon whichI secure the faucet 6, by which I draw off the water in this tank.

In the funnels 8 I place the removable or stationary strainers 19,through which the milk can be strained into the milk-cans. These funnelsare secured to the bottom of the ice and waterpan, and when I removethis pan they come with it. In the bottom of this re frigeratingpan Ilocate suitable pipes, 20, to conduct the cold water down around theexterior of the milk-chambers or about the tank, and these pipes 20extend above the bottom of the pan, so as to insure a certain depth ofcold water thereon when desired.

21 is the general ventilating-shaft, and 22 is a draw-off pipe from theice or Water pan.

I am aware that cylindrical milk-cans having in one side a verticalrecess extending about twothirds the way up from the bottom, and havinginclined and converging sides to the recess and a rounded back and. anupwardly-inclined top, have been heretofore invented and patented; butthat is not my invention.
